Granite Specifications

Granite is one of the most durable and attractive of all natural stones. It is quarried in many countries across the World and consists of quartz, feldspar and mica; during formation it cooled very slowly which results in it being second only to diamonds in its hardness. Due to its resistance to flaking, scratching and scorching, granite is the number one choice in natural stone for contemporary floor coverings, wall tiling, kitchen worktops, bathrooms, wet rooms and commercial applications. Available in a wide range of surface finishes to suit the project brief, granite will add elegance to any room or space. We recommend sealing the surface to ensure that it remains in pristine condition.

The following technical information may be of interest to Architects, Interior designers and Specifiers; the product weights and Physical property tests refer to the three types of granite that form the core of our product range.

The weight of granite

Silver grey and Beige granite weigh 2700 kg per cubic meter.
Dark grey and Black granite weigh 2900 kg per cubic meter.

For example, a Silver grey paving slab measuring 40 cm x 40 cm x 2 cm thick would weigh 8.64 kg.
Calculation: 0.40 (width) x 0.40 (length)  x 0.02 (thickness) = 0.0032 cu. meters x 2700 kg = 8.64 kg
